static <B> ImmutableClassToInstanceMap.Builder<B> |
builder()
Returns a new builder.
|
static <B,S extends B> |
copyOf(Map<? extends Class<? extends S>,? extends S> map)
Returns an immutable map containing the same entries as
map. |
protected Map<Class<? extends B>,B> |
delegate()
Returns the backing delegate instance that methods are forwarded to.
|
<T extends B> |
getInstance(Class<T> type)
Returns the value the specified class is mapped to, or
null if no
entry for this class is present. |
static <B> ImmutableClassToInstanceMap<B> |
of()
Returns an empty
ImmutableClassToInstanceMap. |
static <B,T extends B> |
of(Class<T> type,
T value)
Returns an
ImmutableClassToInstanceMap containing a single entry. |

map. If
map somehow contains entries with duplicate keys (for example, if
it is a SortedMap whose comparator is not consistent with
equals), the results of this method are undefined.
Note: Despite what the method name suggests, if map is
an ImmutableClassToInstanceMap, no copy will actually be performed.
